To al! tzr/"mm it may concern.'

Be 1t known that I., C1-mamas A. L. SAUN- Dnns, a citizen of the United States, residing at Elgin. in the 'county of Kane and State 5 of Illinois, have inventedeertain'new and useful Improvements in Shoe Liners, of which the following is arlescription.

In making shoes, it is customary to secure the outer sole to the inner sole or insole, by

sewing. nailing or vthe like, so that a row .f of stitching or'nail points appears on the insole, and over this vinsole is arranged a false lining, so as to make the bottom of the shoe smooth and .prevent physical discomfort. to

the wearer, or excessivev wear on the hosiery,

and for other reasons well known in the art.

This false lining is generally placed into the shoe by hand, holding it concave so that its cemented surface will not., contact with the correspondingly cemented surface of the shoe bottom until the parts are in the desired position for assembly, whereupon the lining is spread out. smooth and pressed against the bottom of the shoe so as to prevent wrinkles, if possible. It is ,obvious that it is extremely diicult to place such liners in the shoe with' any degree of rapidity, and it is much more difficult to do so when 'handling narrow shoes. f Y

.One ofthe objects of my'invention is to provide an improved means for holding the liner in position while the shoe is placed with its bottom,in juxtaposition to the ce- `mente'd surface of the liner, whereupon thel To this end my invention consists in the' novel construction, arrangement and com-v bination of parts herein shown vand described, and more particularly pointed out in the claims.

'i Fig. 1 3` ,is a top plan'r view of vention.l there is shown a` hollow ljack'lwith. a shank portion 2. It will Vbe notedthatthe jackis concave .on its upper surface in transverse cross-sec`tin,as indicated at 3, `'so thatv 85 when thelineror lining sheetisarranged thereon with its cemented side uppermost,- f

said cemented side will be out vof contact with the correspondingly cemented inner surface of the bottom ofthe shoe 5. f Open.; ee I Y* ings yor perforations 6 are *provided-'ini the concave iippersurface .of the jack 1, said openings communicating with the hollow interior of the jack. i 'l Secured tothe rear vend ofthefj'acklis a "95 heel plate 7,` said heel plate being movable relative Vto said jack and hinged thereto atfitsl inner edge, as at S. sothat when the shoe 5 `is slipped over the j ack, the heelplate 7 may be arranged out ofthe way 'to' the lposition l shown in full lines in Fig. .7,.so that the per of the shoe will not be un'rlulviniured when slipping ysaid shoe onto the jack. After the shoe has been slipped on 4the jack, ,theV

Fig. l is a front elevationof my. improvedy heel plate T is moved into operative position, as shown in dotted lines in Fig. 7, which movement causes the shoe to slide longitudinally relatively to the jee-lr, so that the toe portion of the jack is moved to the proper distance'from the heel of the shoe; or in other words, when the heel plate 7 is moved to the dotted line position shown in Fig. 7, the lining` sheet 4. is in proper position for its securement to. the inner surface of the bottom of the shoe.

ln order to securely hold the lining sheet l in `position on the iaclr while the shoe is slipped into position, l have provided suction means produced by a pump 8 or the lilre, arranged at any suitable point, the intalre 9 of said pump leadingr from the'interior of the hollow jack, the conduit means therefor comprisinga pipe 10 secured to the shank portion 2 of the jack by threading or in other suitable or equivalent manner. At the discharge outlet 1 of the pump there is arranged a conduit or pipe 12 communicating,` with the pipe 10 adjacent the upper end thereof so that, as will be hereinafter described, the upper portion of the pipe 10 between said junction and the jack is both a suction pipe and ay discharge pipe, successively. y

Between the pump and the juncture of the pipes l and 12, there are arranged valves 13 and 14C, one on each of said pipes, said valves being of the gate type, as shown in Figs. il, and 6 c r of any other desired type. whereby the flow through said pipes may be opened or shut off as desired. On each of the pipes and 12 and intermediate the vpump and the aforementioned valves, is

mounted a valve 15 and 16, respectively. These valves are of theV tlapper type as shown. or of any suitable or equivalent structure. whereby atmospheric air may be `drawn into said pipes 10 and12.

The valves 13 and 14 each have a controllineV arm or lever 17 secured thereto at one end. the other ends of said levers being pivotally connected to a movable bar 18. The bar 18 is provided with a slot 19 intermediate its ends. and through said slot is inserted the end ot one arm of a bell crank lever 20-21 said bell crankv lever being secured to a rock shaft 22 pivoted to a. suitable supporting frame, which may be ot any desired or preferred construction. Arms 23 and 24 are also secured to the rock shaft 22, said arms being` adapted to alternately engage and operate the fiapper valves 15 and 16, as shown most clearly in Figs. .1 and 2.

The valves 1,3 and lil are so arranged that theyalso operate successively. that is, when one is open the other is closed. To the free end of the bell crank arm 21 is secured a connecting rod 25 operated by a. treadle or foot lever 26.

The heel plate 7 has a rod 27 pivot-ally secured thereto (Fig. 7), one end of said rod being), secured to a sleeve 28 encircling the upper portion of the conduit 10 and acting as a vertical guide therefor. A second rod 27" is pivoted to the lower end of said rod 27 and to the sleeve 28, the other end of the rod 27 connected to one arm of a bell cranklever 29-30. 'The bell crank lever 29-30 is pivoted at some suitable fixed point, as for instance, at the upper end of the conduit 12 (Fig. 1), so as to control the movement of the heel plate 7, and the free end of the arm 30 of the bell crank lever is pivotally secured to one end of a connecting rod 31, the.

other end of the connecting rod being secured to the treadle 26. A spring 32 is preferably arranged to cooperate with the treadle 26 to return it to its inoperative position after the operation thereor.

rlflie operation of the device is as follows: Assuming' that the jack is in the position shown in F l7, the lining sheet 4 cemented on its upper surface, is arranged over the upper surface of the jack, with the heel plate in its inoperative position. At this time the valve 13 is open and the valve 14 closed, and the flapper valve 15 is closed and the valve 16 open. Hence the pump will exert a suction on the lining sheet to hold it firmly in place so that theshoe may be arranged on the jack in proper position for the sec-ureinent of the liner to the cemented inner surface of the bottom of the shoe. Then the trea dle 26 is pressed, first throwing the heel plate 7 into operative position, which moves the shoe longitudinally relative to the liningr and the jacli. if the shoe is not already in the proper position. and with continued movenient of the treadle, in the same direction, the valve 13 closes and the valve 14 opens, and at the same time the vlave l5 opens and the valve 16 closes. so that air is drawn in through the open lapper valve 15 and discharged through the openings in the hollow jack. spreadingF the lining sheet flat and l'orcibly pressing it against-the cemented surface of the inner surface ot' the bottom of the shoe. whereupon the treadle may be released and the shoe removed off the jack.

lt will be noted that when the heel portion is forced upwardly Yinto proper operative position into the lieel of the shoe, it forces the toe of the shoe forwardly the proper distance from the heel of thejack. The i aclrs may he made in pairs. that is, one for the rightshoe and one for the left,and of suitable designs and sizes for the particular shoes to be opera-ted upon.

ln Figs. 7.2 and 13 there is shown a modi- .lied `torni of jack. that shown being intended for the securement of heel pads to the insoles, These pads may be of felt, leather, or an;7 desired material, and are applied in a manner similarly to the securement of the liners just described. The jack 33 is hollow and-communicates with a conduit l0', sim-v ilar to the conduit l0.'` vOpenings 34 are providedin 'the' upper surface of the jack so that suctionor pressure may act on the heel pad placed onvthe. jack. yIn this modication. the' top surface' of the yjack is straight lor plane, `but it may be concaved similar to the concave surface, of the: jack l, if so desired.i l Y u' The pad with cement on lits top is placed on`A the jack 33 and held by suction: Then the shoe is slipped intoposition vand air vpressure applied to'force the pad against the heel portion the heel bottom'.v

It isobvioiis that the jack 33 land alsothe jack l, may be portable or movable. if desired, and inserted into the shoe, the pad being held on the jackby suction. When inserted, air pressure is applied to `force the pad home, andthejack then removed for the next. shoe. i

'Having thus described" my inventionvit is obvious that various immaterial'f'rnodiiications may' be made in the ysame without departing from the'spir'itof'my invention; hence I do not wish to be understood as limiting myself to t-he exact form, construction, arrangement and combination of partsy herein shown and described, or uses men-` tioned.
